H. J. LEIDEL TIRE TOOL Filed Jan. 29, 1941 INVENTOR HAROLD I LE/DEL ATTORN EYJ appears in the first phaseof operation,

able with ordinary tire tools.

I 'Patented Aug. 10, 1943 r t Harold .L Leidel,Wadsworthg'Ohio ss ss-tram. i%1 6 450 a s 1 (3 Claims; o1 j 157.-.6) "jj This invention relates to tire toolssuchas are used to effect the removal of wheel casings'irom drop center tire rims, andmore especially itree lates totire tools for the removal of tiresirom a' new type of rim wherein-the tire-beadsare Ie-,

ceived in shallow circumferential channels or 'gr'oovesin the rim. It will be understood, lciow ever, thatthe tool is notlimited in its applicatioh to the particular wheel rim described} but that it'may be advantageously used on other types of Wheel rims. I j The chief objects of the invention. are to pro- 7 vide'an improved tire tool of the characterrmentioned that will be simple in construction; that may be manufactured and sold atrelatively low price; and which will-be capable of exerting powerful leverage upon the bead portion of a wheel mountd upon a tire rim.- Other objects will be manifest as the description proceeds a s V Of the accompanying drawing v Figure 1' is afragmentary sectional viewof a drop center rimjof the type hereinbefoi'e referred" to, and a' tire thereon; andithe improved tiref tool casing place after thetire isf de fl ated so thatja 7 v e ar s-mast-bri he' eli e ew-@ trol'and to a safe stopin oaseof blow-out or .punc

The ti re-is designated as a whole by the numeral J4, and includes fthe usual wire bead reinforcement i5 whichcis characteristic of cept by the application of asubstantial force, which force is greater than that usually'obtain- Formed along the inner margin of each bead seat i2 is a low circumferential rib I! which is a distinguishing characteristic of rims upon which the improved tire tool is designed to operate.

' The purpose of .the rib l! is to retain the tire 24, that extend longitudinally there rim. Consequently a .-t1 employed for forcing a t no m n s :esiol withstand the strainsincidental to operation; and
